. LASTING IVIACHINE.

Application led December 23, 1918. Serial No. 267,973.

To all wiz-0m t may concern:

Be it known that ORRELL ASHTON, late of Swampscott, in the county ofEssex and State of Massachusetts, deceased, invented certainImprovements in Lasting Machines, of which the following description, inconnection with the accompanying drawings, is a specification, likereference characters on the drawings indicating like parts in theseveral figures.

This invention relates to that class of shoe machinery known as lastingmachines, and especially7 to machines of the type in which the shoe ismoved to cause the' work-engaging instrumentalities to operateprogressively around the margin of the shoe, as distinguished frommachines of the typein which the toe end is lasted by a single operationand the heel end likewise lasted by a single operation.

ln the manufacture of shoes of some types it is desirable to coat thebottom face of the insole with adhesive substance prior to pulling overthe margin of the upper, relying upon the adhesive coating, rather thantacks or other fasteners, to hold the pulled-over margin on the faceofthe insole until the operation by which the outsole is permanently7lsecured to the upper. It frequently happens that the adhesive coating ofthe in- Sole becomes considerably dried before the margin of the upperhas been pulled over, with the result that the coating becomes verytenacious. This condition ofthe coating renders the pulling-overoperation more difficult, particularly when the upper is lasted by awiping'action. Incidentally to a wiping action, the upper is bent overthe edge of the insole and is pressed upon the face of the insole beforeit has been drawn to the intended degree of tightness against the last,and if the coating on the face of the insole is very tenacious. at suchtimes it will materially oppose the creeping of the upper and cause thewiper to slip without fulfilling its upper-tightening function.

The present invention is shown by the aocompanying drawings as beingembodied in a machine comprising a device arranged 'to end the margin ofthe upper over the edge of the insole, and to press the bent-overportion against the face of the insole. This device, under conditions tobe described later,

has the action of a wiper, and, for conven ience,the latter term isapplied to it, although, under conditions to be described first, itsaction is not that ofa. wiper. The machine as shown comprises a gripperarranged to act conjointly with the wiper'to grip the upper and to pullit over the face of the insole without touching it to said face untilthe overdraft has been completed. As shown these instrumentalities areactuated in such manner .that the wiper does noty eX- ercise itsfunction of passing the pulled-over portion against the face of theinsole until after the upper has been drawn tightly against the last,thus avoiding whatever opposition the aforesaid adhesivecoating on theinsole might otherwise offer to the draw. ing of the upper.

The wiper is, for vthe purposes Vabove stated, under the! stress of aspring'that tends normally to press it against 'theface of the insole,and the gripper thatV co-acts with the wiper is under the stress of aspring that maintains the gripping action. Also, incidentally to thepulling-overaction, the upper is drawn tightly about the last, then,being incapable of following the gripeV ping elements after having givenup allr its slack, the pulled-over margin slips from the grip of thegrippers, and as soonas. it has' escaped from such grip the wiperrespondsL to the stressof itsspring to niove the pulledover portion intocontact with the adhesive coatingand to press it against the face of theinsole. The margin of the upper is thus assured of being pulled over asfar as the last will permit before being permitted to contact with theadhesive coating, the subsequent pressing of the pulled-over portionagainst the face of theinsole being executed so closely upon the escapevof the upper.

from the grip of the gripper that the upper has no appreciableopportunity to lose the tension applied to it by the gripper. Thistension is maintained in part by anedge rest against which the shoe may*be held during the operation described, said edge rest being arrangedkto press the upper against the edge of the insole.

The pulling-over operation above described is intended Yto be practisedon the forepart and shank portion of the shoe-after the heel end hasbeen lasted, and may also be practised on the heel end if desired.Ordinarily, however, it would be suliicient to rely, so far as the heelend is concerned, upon the simpler and more rapid operation of wipingthe upper over the insole without gripping it. This is accounted for bythe fact that the necessity ior tightening the upper about the last doesnot apply to the heel end excepting as to tension lengthwise of theshoe, and this tension cannot begin until after one end has been lasted.In order, therefore, to dispense with the gripping action at the heelend, and to expedite and improve the lasting of the latter, I haveprovided the machine with other means for co-operating with the wiper tolast the heel end before lasting` the other parts. By following thisorder of procedure the machine will have the benefit or the grippers totake up whatever slack may be necessary to tighten the upper after theheel end has been lasted.

For the purpose of promoting the lasting of the heel end as aboveoutlined the machine shown is provided with a work-rest ar ranged tosustain the heelpart ot the shoe to the action of the wipers, and isfurther provided with driven mechanism arranged to move the work-resttoward the wiper, while the latter is overlying the wiped-over portion,to cause supplemental pressure of the wiped-over portion against thecoated face of the insole. Inasmuch as this part ot 'the lastingoperation does not require the gripper in the vicinity of the wiper themachine is provided with a detent arranged to hold the gripper away fromthe wiper to avoid interference with the latter, and to enable theoperative to manipulate the shoe without interference trom the gripper.This detent may be moved to release the gripper whenever it is desiredto call the y latter into play.

The aforesaid work-rest, which is intended to be used only whenoperating upon the heel end, is mounted in such manner that it may bemoved to and Jfrom its work-sustaining position, and a detent isprovided for holding it in said position. rlhis detent also is capableof being moved to release the work-rest so that the latter` may move to:i remote position where it will not interfere with the manipulation ofthe shoe while the forepart and shank part are undergoing their part ofthe lasting operation.

The work-rest is supported by a carriage that is Lactuated periodicallyto apply the aforesaid supplemental pressure by which the wiper-overportion of the upper is pressed against the :ta-ce of the insole. Forreasons that willI appear the work-rest is preferably made in twosections one ot whichwill engage the work, and the other of which willholtA the work-engaging section. This sectional construction permits theintroduction of a cushioning spring as a backing for the work-engagingsection, and permits the work-rest, as a whole, to be shifted relativelyto the carriage without alteration of the applied stress of thecushioning spring. The workrest may, therefore,

be moved to and from its operative position without affecting otheradjustments.

As another feature of the invention the wiper is preferably divided intoa plurality ol' sections, the latter being movable relatively to eachother so as to be capable of exerting their pressure against the tace otthe insole independently of each other, the several sections of thewiper being thus capable olz compensating for variations in thethickness of the pulled-over portion at ditferent points, and being thusadapted to apply their pressure with substantially uniform degree,notwithstanding such varia tions in thickness. Both sections of thewiper, the latter having only two sections in the example shown, co-actwith one gripper, the latter acting conjointly with each of th wipersections to grip the upper.

When lasting the iorepart and the shank portion'it is necessary to tiltthe shoe to various angles in yorder to do the work thor oughly andeliiciently, but it is nevertheless desirable to have someinstrumentality arranged to determine a suitable. working position orcthe part being worked. ln view ot this reason the invention provides asolerest that may be locked in work-sustaining position when theaforesaid worlerest is retracted to its remote position. The sole-restis, however, supported by a fixture relatively to which it is movable,and a spring is arranged to exert Vits stress normally to move thesole-rest to said position, but the solerest will be fixed or yieldingaccording to whether a locking device with which. it ie provided is inor out ol' locking position. ln practice, when operating with the aid ofthe heel part work-rest, the sole-rest may bear upon the tace'ot theinsole, but will preferably be unlocked so that it may yield in responseto the movement ot the heel part work rest that causes the supplementalpressure of the wiper upon the wiped-over portions.

It has been stated that the gripperis provided with a dctent to hold itaway from the wiper, and that the work-rest is provided with a detent tohold it in work-sustaining position. ln practice these two detents arecalled upon to function at the same time. and their periods ol nonuseare co-extensive. ln view ot this condition the inven tion provides thesaid detente with connections by which they may be moved in unison torelease the gripper and the work-rest collectively, thus enabling theoperative to etect the release of both by one operation instead ofhaving to perform two separate re- (Us U..

Referring first to Figs. 1, 2 and 3, a standard is indicated at 15, andthe frame of the wiped i the upper over head is indicatedas a whole bynumeral 16. i shaft 17 is mounted in suitable bearings in the head'andis provided with a Ytight pulley 18 which is driven through a belt 19 bysuitable clutch mechanism of wellknown construction (not shown), underthe control ol' the operative. A brake-rod 2() connected to theclutch-controlling mechanism is arranged to act on pulley 19 to stop thelatter when the gripper, hereinafter described, is initsextreme upwardand extreme forward position.

They heelpart work-restv comprises twoA telescoping sections 21 and 22,and is mounted as a unit in a vbracket 23 formed upon a carriage 24.This carriage is mounted lto slide up and down on guides 25 formed upona part of: the head 16. The Astructural details of the work-rest areshown best by Fig. The work-engaging portion ot the work-rest includes astem 26, the latter being arranged to slide in the section 22. Thelatter section is tubular and serves as arholderY for the work-engagingsection. Bracket 23 is bored to receive section 22., the latter beingadapted to slide up and down in theA bracket. A flange 22X is formed atthe lower end of section 22 to prevent the latter from being withdrawnupwardly from the bracket, and serving to. limit the upward movement ofthe tubular section relatively tothe bracket by striking the bottom faceof the latter.` As shown by Fig. 1', the workrest is in its lowerposition relatively' to the carriage, but as, shown by Fig. 5 it is. inits upper or potential'work-engaging position relativelyv to theCarriage. Section 22 is provided with an external annular groove- 27 toreceive a detentY 28 asshown by Figs." 5 and 7, the detentbeing'carried` by the carriage and connecte-d to thelatter by aV pivotmember 29. A spring hereinafter identifiedl is provided for moving thedete'nt into groove 27 when the lattervis in Vregis-v tration with thedetent.

The holder section ofthe work-rest is` bored to provide a cavity` 30 forthe reception of stem 26 and a cushioning spring 31. This cavity extendsto the top of the holder but .does not extend to the bottom. The bottomis, however, bored and tapped for the reception of a screw 32 by whichthe applied stress of spring 31 may be regulated. rllhis spring isvcompressed between .the stem 26. and ahead 33 carriedfby the'inner endof' the regulating screw. TheA work-engaging sec-tion ot the work-restis held in the holder section by a screw 341, said screw being fixed instem 26 and extending radially therefromthrough a slot 35 inthe holdersection. The purpose of ther slot isV to enable the work-engagingsection to yield relatively to the holder section when the carriage is Ymoved toward the wiper.

The carriage 24 1s moved upr and down by lil a reciproca-tory rack 36.The rack is actuated periodically by a cam hereinafter dcscribed. Theconnection between the rack and the carriage provides for adjustment ofthe latter relatively to the rack to take care of lasts of differentdepth. For this purpose a rod 37 is aflixed to the carriage, and asleeve 38 is mounted on the rod and adapted to be rotated. This sleeveis provided with spur teeth 39 at Vone end, said teeth being in meshwith the teeth of rack 36. A. hand-wheel 40 is fixed to the other end ofthe sleeve, and by turning the hand-wheel the carriage may be adjustedup and down relatively to the rack. In order to maintain the adjustmentprovision is made for locking the sleeve against rotation, suchprovision comprising a stationary disk 41 fixed to rod 37. This disk ispartly enclosed within the rim of the hand-wheel, and the confrontingfaces of the disk and hand-wheel are provided with locking teeth 42represented by dotted lines in Fig` 1. Referring now to Fig. 14, thesleeve is capable of t moving endwise to connect and disconnect thelocking teeth, but such movement does not disconnect the teeth 39 fromthe teeth of the rack. `When the hand-wheel 40 is moved to the right thelocking teeth are engaged with each other in loclring relation, but whenit is moved to the left the teeth are disengaged and the sleeve isunlocked so that it may be rotated to adjust the carriage up and down.

A link 43 connects the rack 36 with an operatinglever 44 of bell-crankform. The fulcrum stud of this lever is indicated at 45. A cam roll 46carried by the lever rides on the face of a cam 47 carried by shaft 17.The effect of the cam is to lift carriage 24, the force of gravity beingsufcient to nieve the carriage inthe opposite direction and to keep thecam roll seated on the cam.

The margin 0, of the upper of an unlasted shoe is bent over the edge ofthe insole c by a wiper, the latter comprising, in the present instance,two component sections 48, 48. These wiper sections are arranged side byside as shown best by Figs. 4 and 6. They are mounted upon a pivot stud49 that is carried by a reciprocatory bar 50. This bar is movedpositively in opposite directions by a cam 51 carried by shaft 17.Operating connection from the cam to the bar is formed by lever 52. Thelower end of the lever is connected to the bar by pivot pin 53, and thefulcrum pin, indicated at 54, is fixed to the lever and has slidingconnection with a part of the head 16. For this purpose the head isprovided with aslot 55 in which the fulcrum stud moves.

The vwiper sections bear normally on a rotary anti-friction bushing 56mounted on a pin 57. This pin is supported by a part of the head 16. Thewiper sections are movable up and down relatively to and independentlyof each other so that each of them may take a position according to thethickness of the stock engaged by it without regard to the positiontaken by the other vfor this purpose a single regulating screw 60 isarranged to regulate both springs. As shown best by Fig. 6, screw 60 isscrewed into the bar 50 from the upper side, the bar being bored andtapped for that purpose. rihe lower end of the screw bears on a follower61, and the latter, in turn, bears on the upper end of one of thesprings 58. A collar 62 formed on the head of the screw bears on afollower 63, and the latter bears on the other spring 58. j

Although the wiper sections are normally pressed downwardly by thesprings 58, they are adapted to be pressed upwardly by the work when thelatter is lifted by the slide 24. in this connection it may be statedthat the applied stress of spring 31 of the workrest is greater than theaggregrate stress of springs 58, .and that the wiper sections, ratherthan the work-rest, yield until the upward movement of the wipersections is arrested positively by a stop face 64 of bar 50. Fig. 18shows the wiper sections as being pressed against said stop face inconsequence of upward movement of the work-rest, ythe wiped-over portionof the upper being subjected to the applied force of spring 31 and beingpressed against the face of the insole with a. pressure of correspondingdegree.

Cams 47 and 51 are timed in such relation that the work-rest occupies alower position whenever the wiper is retracted from the work as shown byFigs. 1, 8 and l11. On the other hand, when the wiper is advanced to theposition shown by Fig. 13 cam 47 acts to lift the work-rest, the shoebeing thereby pressed against the wiper kafter the latter has reached aposition where it may bring the spring 31 into play to applysupplemental pressure to the bent-over margin of the upper. The primarypressure of the wiper is applied by springs 58.

Although the members 48, 48 are usable as a wiper, they are usable alsoas gripping members, their leading ends being formed and arranged to actconjointly with a gripper65. rEhe gripping portions of the members 48are smooth, but that of gripper 65 is preferably roughened and may be soprepared by forming transverse grooves. The generalv contour of thegripping face' of gripper 65 is preferably lconcave so that the lowerextremity may underlie the wiper sections sufficiently `to lift thelatter against the stress of springs 58. The gripper 65 is xed to a bar66, this bar extending through a guide-sleeve 66X and being adapted toslide up and down therein. The upper end of the bar is connected by apivot pin 68 to an operating lever 67. In the present instance thefulcruln stud of bell-crank lever 44 serves also as the fulcrum stud oflever 67. This lever is continuously under the stress of a spring 69that tends normally to move the gripper' downwardly, upward movement ofthe gripper being effected by a cam 70 carried by shaft 17. The cam actsupon a roll 71, and the latter is carried by a slide 72 arranged toslide up and down in suitable guides formed on the head 16. Al rod 73 isfixed to the slide and extends upwardly through a stationary bracket 74.Spring 69, which, is helical in form, surrounds rod 73 and is seatedupon bracket 74. A collar 7 5 fastened to the upper end of the rod bearsupon the upper end of the spring, the latter bein compressed between thecollar and the l brac (et. The stress of the spring is thus applied tolift the rod and the slide, and cam roll 71 is thereby held in contactwit-h cam 7 O. The rear end of' lever 67 is connected to rod 73 by acolla-r 7 6, the collar being loose relatively to the rod and beingconnected to the lever by trunnions 77. When the slide 72 is raised bythe spring the upper end of the slide abuts against the lower face ofcollar 7 6 and thereby moves the lever to lower the gripper. When slide72 is moved vdown` wardly collar 76 is depressed by a collar 7 8, thelatter being fixed upon rod 73 by a set screw 79.

The gripper' is moved toward the front by a cam 8O carried by shaft 17.This cam acts upon a roll 81 mountedupon a rod 82. This rod is arrangedto move endwise in suitable bearings in the head 16, and is under thestress of a helical torsion spring 83 that tends tomove it always to therear, or to the right, as shown by Fig. 1. Spring 83 is provided with aregulating device by which its applied stress may be varied. For thispurpose the spring is connected to rod 82 by a lever 84, the rod havinga projecting Stud 85 against which the lever bea-rs. The lever isarranged to oscillate upon a fixed stud 86, and is provided with a lug87 against which one end of spring 83 bears. The other end n of thespring is anchored to a regulating handle 88. This handle is arranged toturn upon the stud 86, and is provided with a pawl 89 that co-acts witha fixed ratchet 90. The ratchet is shown as being fixed to stud 86. Thespring may be wound up to any desired degree of stress by moving thehandle 88 in a clockwise direction about stud 86, pawl 89 serving toprevent rotation inthe opposite direction.

Bod 82 carries a forlrQl at its forward end, said forkY straddlingsleeve 66X and beingconnected to the sleeve by a pivot pin 92. Lever 67and rod 82 are actuated in such timed relation as to impart a compoundmovement to theV gripper, the latter being moved to the rear by spring83 to grip the upper in consequence of spring stress rather than inconsequence of any positive action. This enables the gripping stress tobe regulated' so that the upper may slip from the grippers after beingdrawn tightly about the last, and in practice itis desirable, for somepurposes, torpermit such slipping so. that the stress of the wipersprings 58 may be utilized to press the pulledfover portion of theupperagainst the face of the insole in consequence of the escape of saidportion from the gripper. Y Y

The gripper is shown by 'F ig. 1 as having descended on its way to gripthe upper against the wiper sections. According to this figure the wiperis retracted to the right as far as it will go, in which position itsleading end is behind the work-engaging portion of an edge-rest 93. Thegripper proceeds from the position shown by Fig. 1 in a directionindicated by arrow r, such motion being imparted by spring 83. TheInargin of the upper is thereby gripped as shown by Fig. 8. Thewiper-bar or carrier is then moved positively toward the left, and atthe Same time gripper is lifted by its cam so that its lower end followsa path represented by arrow s. The motion from right to left draws theupper tightly about the last and pulls the margin of the upper over theedge of the insole, while the upwardV motion of the gripper keeps thepulled-over portion of the upper out of contact lwith the face of theinsole. `The overf draft of the upper is, therefore, free from allopposition from whatever adhesive subment. lt follows, therefore, thatthe wiperescapes from the gripper 65 coincidentally with the escape ofthe upper, and the springs 58 assert themselves immediately to force thewiper sections downwardly and thereby press the pulled-over portionagainst thek face of the insole. The result of this action is shown byFig. 10. If the face of the insole is coated with adhesive `substancethe latter will hold the pulled-overportion So pressed against it. Thegripper, as shown by F ig. 10, is in its initial position, and remainsthere while the wiper is retracted to its initial position as shown byFig. 1.

A sole-rest 9&1 for determining the planel of the work relatively to thegripping members is aiiixed adjustably to a sliding block 95. This blockis arranged to slide up and down in suitable guides in a holder 96 whichis atlixed to a stationary bracket 97, the latter having a slot 98through which a clamping screw 99 extends. The holder 96 is bored andtapped for the reception of screw 99, and the latter is adapted, whenloosened, to move up and down in the slot according to the positiontaken by the holder. When the Screw is tightened it clamps the holderfirmly to the bracket. Block is movable up and down relatively to theholder, but it may be locked relatively to the holder by a lockingmember 100. The block is formed with a notch 101 into which and fromwhich the locking member may be moved. The locking member is providedwith a stem 102 arranged to slide in a suitable bearing formed in holder96. The range of movement of the sole-rest is limited by a pin 103, saidpin being arranged in a hole bored through holder 96 and occupying anel0ngated notch 104 formed in the block. According to the structureshown notch' 101 occupies a position in registration with locking memberwhen the block is as low as retaining pin 103 will permit. The lockingmember may then be inserted into the locking notch or withdrawntherefrom.

ln practice the sole-rest may be locked when the heelseat work-rest isout of use, but when the latter is in use it is desirable to have thesole-rest unlocked so that the latter can yield to the upward movementoi" the shoe as caused by the heelseat workrest. The block 95 is boredfor the reception of a helical spring 105, and the latter may be putunder compression by a regulating screw 106. This screw is held by afixture 107, the latter being bored and tapped for the reception of saidscrew and being aiiixed to holder 96. A Jfollower 108 is interposedbetween the screw and the spring. Tt, when using the sole-rest withoutthe heelpart worksupport, the locking member 100 be lett in unlockingposition, the spring will serve to keep the sole-rest in the desiredposition unless excessive upward pressure be exerted on the shoe.Ordinarily,

however, the spring would be suiiicient for the purpose, but the lockingmember, in use, guards against the possibility of yielding, howevergreat the upward pressure may be.

It has been stated that the gripper 65 may be held away from the wiperwhen it is desired to use the latter as a wiper and not as a grippingmember. For this purpose lever 67 is provided with a stud 109, and amovable detent is provided for supporting the stud in a raised position.As shown by Figs. 1 and 2, the gripper is in its lowest position, andthe bottom tace of stud 109 is a considerable distance below the. upperitace ot detent 110. When the gripper is in its highest `position thebottom face of stud 109 is as high, at least, as the upper' face of thedetent, so that the latter may be moved horizontally to a position underthe stud. Detent 110 is iixed to a rock-shaft 111, and the latter ismounted in suitable ixed bearing members 112, 112, and in movablebearings 113, 113 carried by carriage 24. A helical torsion spring 114is coiled about the rock-shaft, and its upper end is anchored to theadjacent bearing member 112, while its lower end is anchored to a collar115. This collar is lixed to the rock-shaft by set screw 116. Spring 111tends normally to turn the rock-shaft in a direction that will carrydetent 110 to its holding' position under stud 1.09, its normaldirection o1 rotation being anti-clockwise in respect to Fig. 7.

The rock-shaft 111 carries a second detent indicated at 117, the`function oit which is to hold the gripper in its forward position whenthe gripper is held in its elevated position by detent 110. For-thispurpose the fork 91 is provided with a plate 118 behind which a detent117 is adapted to lie when detent 110 underlies stud 109. Theoscillatory motion by which detent 110 is moved to release stud 109 issufiicient to release plate 118.

The machine is provided with connections from detent 28 of the heelseatwork-rest to rock-shaft 111 for the purpose ot releasing the gripper andthe heelseat work-rest in unison by one operation. Detent 28 is eX-tended to the lett as shown by Figs. 1 and 7 to provide a suitablehandle by which it may be moved Jfrom its holding position. The otherend of' the detent is extended to provide an arm 119, and the latter isconnected by a link 120 to an arm 121. The hub 122 of the latter arm isarranged to slide on rock-shaft 111, and is located between bearingmembers 113 so as to be carried up and down with the carriage 21. Therock-shaft is provided with an elongated keyway 128, in which a slidingkey carried by hub 122 serves to lock the hub to the rockshaft inrespect to oscillatory motion without interfering with the up-and-downmotion of the hub relatively to the rock-shaft. 1n consequence of theseconnections spring 114 is utilized not only to move detents 110 and 117to holding position, but is utilized also to move detent 28 to holdingposition, although the latterdetent moves up and down with the carriage211.

The clutch-controlling mechanism may be like that shown and described inLetters Patent No. 1,254,917150 stop the shaft 17 when the gripper is inits extreme forward and extreme upward position. Detents 110 and 117are, therefore, free to move. to their holding positions in response tospring 11a in consequence of lifting the heelseat work-rest far enoughto place groove 27 in registration with detent 2S. The onlyeffortrequired of the operative for this purpose is that of lifting theheelseat work-rest rela tively to its carriage. lVhen it is desired todiscontinue the use of the heelseat workrest and to bring the gripperinto play, the only eort required is that of moving detent 2.8.

Carriage 2a is provided with a spring plunger 124 arranged to engage theunder face 125 of the heeseat work-rest, to soften the blow of thelatter when it is dropped relatively to the carriage. The carriage isbored for the reception of the plunger, and a cushioning spring 126 isarranged in the bottom of the hole so bored.

In the operation of the machine, for last ing the toe and sides of theshoe, the operator will move the detent 28 provided the last rest is inits upper position, which will allow the last rest to drop and move thedetents 110, 117 so as to bring the grip per member 65 into operation.The shoe is then held up against the bottom rest and laterally againstthe edge rest 93 with the margin of the upper behind the gripper and infront of the wipers 48. The machine is now started by depression of thetreadle to throw in the clutch. The wipers 48 move forwardly, engagingthe margin of the upper in a plane somewhat above the shoe bottom andforce it against the yieldingly held gripper member 65. At first thewipers 418 are supported by the roll 56 but their movement continues thegripper is lifted by its cam and carries upwardly the ends of the wipersA1S and the gripped portion of the upper. This portion of the upper isfirst carried under tension upwardly and inwardly of the shoe, as shownin Fig. 9, the margin of the upper being held out of contact with themargin of the innersole. Finally the resistance of the upper overcomesthe frictional drag of the upper upon the gripper G5, causing the upperto be left behind as the gripper 65 rises and the -l'rictional hold ofthe upper on the wipers #i8 will cause them to be freed from the gripperso that they will be impelled downwardly by their springs 58 to delivera blow or blows upon the upper and force it against the margin of theinnersole, as shown in liI` 10. In the treatment of cemented parts ablow is very effective for securing irin adhesion between theparts.forced into contact by the blow. The operatio-ndescribed is repeated asoften as necessary about the periphery of the toe and sides of the shoeto last all parts of the upper.

At the heel it is not desirable to tension the upper but to lay it incontact with the heel seat by an action which begins at the edge of thesole and extends inwardly to lay the margin of the upper against theheel seat progressively from the edge inwardly. Accordingly, when theheel seat is reached the operator will lift the last support 21 untilthe detent 28 snaps into the groove 27. Movement of the detent 28 willcause the detents 110,117 to arrest action of the gripper member 65, thewipers, of course, being in operation. The work, with the crown of thelast resting on the head 21 of the support, is then adjusted, ifnecessary, as shown in F ig. 11 by pushing the handle t0 and turning itin the required direction. The wipers 4:8 then advance as shown in F ig.12, to wipe in the margin of the upper about the heel seat, and for eachwiping movement the rack 36 is operated to effect upward movement of thelast support and cause the overlaid margin of the upper to be pressedforcibly against the wipers 3S, the upward movement of which is limitedby the surface 64 (F ig. 18).
